bind (SL6)

* A flaw was found in the way BIND handled TSIG authentication for dynamic
updates. A remote attacker able to communicate with an authoritative BIND
server could use this flaw to manipulate the contents of a zone, by
forging a valid TSIG or SIG(0) signature for a dynamic update request.
(CVE-2017-3143)

* A flaw was found in the way BIND handled TSIG authentication of AXFR
requests. A remote attacker, able to communicate with an authoritative
BIND server, could use this flaw to view the entire contents of a zone by
sending a specially constructed request packet. (CVE-2017-3142)

Bug Fix(es):

* ICANN is planning to perform a Root Zone DNSSEC Key Signing Key (KSK)
rollover during October 2017. Maintaining an up-to-date KSK, by adding the
new root zone KSK, is essential for ensuring that validating DNS resolvers
continue to function following the rollover.
